I have a user that is using a Microsoft Elite Bluethooth KB and mouse set. I need to move these items to a new computer and I do not know the PIN number for the device<s> so I can reatach on the new computer. She does not have the original documentation. I am thinking it is 0000 or 1234. I am going ot be replacing the workstation with a new computer and really need to be able to reinstall these for her. Thanks if you can help.
